# LongStream.Builder

`public static interface LongStream.Builder`
`implements LongConsumer`

java.util.stream.LongStream.Builder

A mutable builder for a `LongStream`.

A stream builder has a lifecycle, which starts in a building phase, during which elements can be added, and then transitions to a built phase, after which elements may not be added. The built phase begins begins when the `build()` method is called, which creates an ordered stream whose elements are the elements that were added to the stream builder, in the order they were added.

See also:

- `LongStream.builder()`

## Summary

### Public methods
`abstract void` | `accept(long t)` Adds an element to the stream being built.
`default LongStream.Builder` | `add(long t)` Adds an element to the stream being built.
`abstract LongStream` | `build()` Builds the stream, transitioning this builder to the built state.

### Inherited methods
From interface `java.util.function.LongConsumer`
`abstract void` | `accept(long value)` Performs this operation on the given argument.
`default LongConsumer` | `andThen(LongConsumer after)` Returns a composed `LongConsumer` that performs, in sequence, this operation followed by the `after` operation.

## Public methods

### accept

    public abstract void accept (long t)

Adds an element to the stream being built.

Parameters
`t` | `long`: the input argument

Throws
`IllegalStateException` | if the builder has already transitioned to the built state

### add

    public LongStream.Builder add (long t)

Adds an element to the stream being built.

##### Implementation Requirements:

- The default implementation behaves as if:

      accept(t)
           return this;

Parameters
`t` | `long`: the element to add

Returns
`LongStream.Builder` | `this` builder

Throws
`IllegalStateException` | if the builder has already transitioned to the built state

### build

    public abstract LongStream build ()

Builds the stream, transitioning this builder to the built state. An `IllegalStateException` is thrown if there are further attempts to operate on the builder after it has entered the built state.

Returns
`LongStream` | the built stream

Throws
`IllegalStateException` | if the builder has already transitioned to the built state
